Campbell County Rockpile Museum

Museum of the Powder River Basin

The Rockpile was a landmark for cowboys and now it's a landmark for the museum next to. This quiet museum has a mix of objects and information about homesteading, ranching, farming, coal mining, ancient geology, and American Indians. There are a few hands on displays with old items for children, but a few are still interesting for adults. A back room in the main building is used for rotating exhibits and the empty space there in front of the covered wagons is for events and talks. Don't forget to walk outside to the big white building with a garage door. There are more exhibits inside and outside on the South side of the building.
